Franklin XS439 impeller washer, part number 305462031, is the impeller washer for compatible Franklin XS439 water-truck pumps. This 300-series stainless steel service part is used in both bearing-frame and hydraulic-drive arrangements.
The impeller washer and impeller lock washer are separate parts. Keeping their identities distinct helps you assemble the required hardware for a pump repair without substituting one washer for the other. Match the exact part number to your installed pump before ordering.
